IMPROVBD :sureau-can stranamente. i

invented a new' and useful Improvement in Platform-Gar Stake-Holders; and I do declare that the following is an accurate description thereof', reference' being had to the accompanying drawings, and to the Vlettersfof Figure 1 representsa partial side" view of a' platformca witlisitalie att-ecimed.- I

Figure 2 is. a'lsectional' view of one side of 'a platform-car showing the method 0f attaching the stake...

` p' Figure is a view ofthe apparatus from the top, with tho'loor of the oarcutra'way." The same 'letters of reference refer to similar parts in `each ligure. Y

'ro the sin A, I nach the stake is, by me-.ms of the slamp E, heid iii-place bj the staple-Boxer F, at.

The stake fastened ttiv oneuof the straplbglts'lffbby Q,iewxingX, g. The staple-boltsF.F,Q&c.,^pass througltThe sill A, and' a spiral collar, H, isA 'fitted to them, against which the'alfm Tis forced hy the cams N N,

which are cast upon the arm I.

At the opposite ends ofthese carne N N, they press upon the plate R. -llhrough .the head K,'ot` the arm I,

, I pass n. lever, I1, with :which to put on or takeoil the force or -pressure'f the cams N. y.

( isiaprojection, cast on the plate R, to pevent the arm I from dropping out of place, by allowing'orie of the cams tb rest upon it. yThe plate R is secured to the sill A by-the staple-'bolt P and nut S.

C is Vthenoor of the car, and D again cnt into -the-oor 'to receive the stake when in' an ,uprightposition. W is a nmetal plate, attached to the stake A, to prevent abrasion of `the same when in ahoriaontal position. Tis a stop, suspended at V by a bolt, to preventlthe lever L fromgetting'out of position. Having thus described the construction of my apparatus, I will explain the mode of using it. By pulling the level-'L to the front, after raising the stop T, the pressure of the cams N N against the collar H and the plate R is relieved, which allows' the staple-holte F F,&c., to become loose, so that the stake, A can be moved to the required position, when the 'lever L is pushed back, the stop T.dropped,-and the stake is rmly held. 4By thisy apparatus thestake can he thrown-down easily, no matter how great the pressure of tha lead may be against it when standing perpendicular. A

' What I claim as invention, and desire to secure by Letters Patent, isi 1. 'The larm I, canas N N, collar H, staple-bolts F F, &c., clamp- Ep late ;R, projection 0, stapl e:7bolt 1?,r

nut S, and lever L, for the .purpose designed. I

2. The combination and arrangement of the stake B, the sill A, the gainDV in the oor'0,'the clamp E,

the stapleibolts F F, &c., ythe. collar H, the arm I, th'e head K, the leve;` L, tho cams N N, the'- projection 0,. staple-bolt -P, the plate R, the ring X, and the stop T, arranged substantially as described for `the purpegpx i design ed. i
